Rangers' next Europa League opponents Olympiacos have been hit with a major blow after key Turkish international midfielder Yusuf Yazıcı suffered a serious knee injury.

Philippe Clement's side travel to Greece next week for the latest game in the new-look competition with a tricky encounter against last season's Europa Conference League winners.

But they will be without 45-times capped star Yazıcı who suffered a potential cruciate ligament injury in their weekend defeat to Asteras Tripolis.

He will be assessed this week to discover the extent of the damage but Olympiacos boss Jose Luis Mendilibar admitted it didn't look good.

He said: "Everything indicates he has suffered a cruciate ligament injury, but we have to wait until the swelling goes down to assess the length of time he will be out.

"It is a huge disappointment to him and to us."

And Mendilibar wasn't happy at his side's defeat, which left them in fourth place in the Greek League.

He said: "We have to stop thinking about the difference between league games and European games and treat them in the same way.

"We have to deal with them all. We keep playing nervously after a game in Europe."
